Problems with D3600

[blurpax]

Hello,

I bought a modem/router D3600. Everything is ok, but sometimes (3/4 times in a day) I've a problem.
I can't reach public IP. No web, no ping... I can't open the web panel (http://192.168.1.1) too.

I just can ping the router lan IP address.

All the router's leds are ok.

If I unplug and plug again the dsl cable the DSL link seems go up again, but the problem still persists.
To solve the problem I must power off and restart the router...

I've tried with two D3600...

I'm from Italy and my DSL provider is Tiscali...

Can you help me, please?

Thank you

Hello Blurpax 

If you are connected over Ethernet cord try to use a different one and if you are connected via the wireless you may want to change the wireless channel could be alot of interferences on the wireless channel you are using.  Hope to hear your feedback
